- •
Carbonation depth of C35 standard cured concrete is 56% smaller than that of C25.
- •
Accelerate curing increases carbonation depth of C25 concrete by 61%.
- •
Paint coating can reduce 28-day carbonation depth of concrete by 46% at least.
- •
Carbonation suppression ratio varies with exposure time and quality of substrate.
- •
Exterior paint coating has a longer blockage time and a smaller carbonation rate.
